Adam Clarke on Judges 2:5

They called the name of that place Bochim - The word בכים bochim signifies weepings or lamentations; and is translated by the Septuagint Κλαυθυων or Κλαυθυωνες, bewailings; and it is supposed that the place derived its name from these lamentations of the people. Some think the place itself, where the people were now assembled, was Shiloh, now named Bochim because of the above circumstance. It should be observed, that the angel speaks here in the person of God, by whom he was sent; as the prophets frequently do.
